Abstract: The wear behavior of CFRP laminates with nano-particles dispersed surfaces of Al2O3 or carbon has
been investigated and compared with that of conventional CFRP which is without particles
dispersed surfaces. As a result of comparison, it is shown that the CFRP laminate with Al2O3
nano-particles dispersed surfaces inherently had low coefficient of friction and high sliding wear
resistance. The measured value of specific wear rate was 3.5x10-7mm3/Nm, independently of sliding
time. The wear behavior of CFRP laminates with carbon nano-particles dispersed surfaces has been
more effectively improved. The measured specific wear rate of this material was in the range of 10－
7mm3/Nm in spite of comparatively small amount of nano-particles dispersion, which is relatively
good as tribomaterial. For the successful application of this method, it is essential to explore the
optimum amount of Al2O3 or carbon nano-particles to be dispersed onto prepreg surfaces. The
deflocculation of the agglomerated particles and their homogeneous dispersion and good
impregnation are the key points in this technology.
